Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU64376
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-21127
CWE-ID:
CWE-459 - Incomplete cleanup
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to sensitive information on the system.
The vulnerability exists due to incomplete cleanup in specific special register read operations. A local user can enable information disclosure.
MitigationInstall updates from vendor's website.

EUVDB-ID: #VU64364
Risk: Low
CVSSv3.1: 5.2 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-21123
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows an attacker to gain access to potentially sensitive information.
The vulnerability exists in Intel processors due to excessive data output when DirectPath I/O (PCI-Passthrough) is utilized. An attacker (both local and remote) with administrative access to a virtual machine that has an attached DirectPath I/O (PCI-Passthrough) device can obtain information stored in physical memory about the hypervisor or other virtual machines that reside on the same host.
